Best software for getting facebook email addresses

ok i scanned thru all the threads on this subject and i found 3 that most ppl recommend:

ulead pro
social lead freak
fb lead chef

but most of the threads i found on this subject are old threads. plus i tried using social lead freak and fb lead chef but both kept returning errors. for fb lead pro it keeps telling me that all the groups i'm trying to scrape from are restricted groups but i know thats not ture. some of those groups are actually open groups but it wont let me. maybe these apps do not work anymore.

please i need recommendations for softwares that could enable me to scrape fb email addresses by groups so i can target my email marketing.
